Claims. (Cl. 10S- 367) This invention relates to a means and ymethod forpro- ,tecting rolls of paper, such as newsprint and the like, duringtransit thereof, against damage, more particularly to the ends of suchrolls.

In shipping rolls of newsprint paper and the like, the term newspriintbeing used herein merely for convenience of reference, and not as a termof limitation, such rolls are usually wrapped and in s ome instances areprovided with end caps, generally of paper and sometimes of othermaterials. These rolls of paper are usually shipped from the paper millsto the consumer, in ordinary railroad boxcars, The rolls are stood onendand according to size, there may be thirty-tive rolls, more or less, ina carload. Upon arrival at their destination, it is veryl seldom thatall the rolls `arrive in acceptable undamaged condition. There arepractically ,always a number of rolls of which the ends are badllydamaged, these being the ends on which the rolls stand during shipment.Depending on the extent of damage the rolls are either entirely rejectedor else are re-rolled to eliminate the damage. The damage is often inthat the ends are worn or pounded down, generally referred to asllattened, and, therefore, cannot go on the press where they are to beused, unless rerolled. This damage has long been a matter ofconsiderable loss and annoyance and a solution to the problem `has longbeen sought.

These rolls of paper are so packed in the cars for shipment that theyhave a certain amount of room for movement, this being very small butenough so that when the car is shifted around and also during the travelof the car on its rails, the rolls tend to shift towards each other. Ihave discovered that this tendency towards slight shifting, while it isunavoidable, and in a sense necessary, is the reason for the damage. Thecars in which the rolls are shipped are not always used only for theshipment of these rolls of paper but are used for shipment of all sortsof cargo. Generally, the floors of the cars are rough. I have discoveredthat if a means is provided whereby the rolls of paper can slide ontheir ends on the door of the car, the little distance of movement theyneed, that instead of the ends becoming llattened or otherwise damaged,the rolls larrive in perfect condition. lt is the lack of ability toshift around smoothly and slide over that causes the rolls to grindtheir ends on the iloor or to grind their sides against the sides of thecar and to thus become damaged on the ends or on the ends and sides. Theregular jolting action of the car when riding along on the rails tendsto make the rolls dance around on their ends, which normally they areprevented from doing and thus become damaged.

With ythe above and other objects in view, my invention consists in thearrangement, combination `and details of construction disclosed in thedrawing and speciiication, and then more particularly pointed out in theappended claims.

In the drawing:

`Figure l is a horizontal section showing diagram- 2,812,727 PatentedNov. 12, 1957 matically a freight car having a plurality of newsprintrolls mounted therein.

Figure 2 is a fragmentary sectional View on an enlarged scale taken onthe line 2-2 of Figure l. i

Figure 3 is a fragmentary sectional view on a further enlarged scalesimilar to Figure `2.

Figure 4 is a perspective View of one of the covering sheets for the caroor.

Referring to the drawing, the numeral 10 designates generally a freightcar and the numeral 11 designates the floor ofthe car 10. A plurality ofnewsprint rolls 12 are placed within the car 10 and are normally set upon end substantially after Ithe manner shown in Figure l'. VIn themovement of the `car 10 from the consignor to `the consignee, the car 10is subjected ot severe jolts due partly to the roadbed and partly to thestopping and starting of the train. These jolts to which the car 10 issubjected cause the rolls 12 to .shift within the car, and this shiftingmovement causes the bottoms of the rolls to become damaged. The damageto the bottoms of the rolls and also to the sides of certain ones of therolls which rub on the sides of the car 10 is frequently Such as torequire rewinding of the rolls so as to eliminate damaged portions of`the paper, and it is not unfrequent that a very substantial amount ofpaper is affected.

In order to provide a means whereby the rolls 12 may `be permitted tohave slight movement on `the floor r11 `of the `car 10,` lhave provideda sheet 14 which may be a paper or fibrous sheet which is laid flat onthe iloor 11 of `the carlo.

The upper surface of the sheet 14 is provided with a relativelyanti-friction surface 15, andthe surface 15 may be formed by coating orimpregnating the sheet 14 with wax, lamp black or other material whichwill produce a relatively slick or anti-friction surface. It will, ofcourse, be understood that the side walls 13 of the car 10 with the endwalls 16 may also have coated sheets 14 secured thereto so that thesides of the rolls 12 will contact with the sheets on the inner surfacesof the side and end walls of the car. It is the practice to cover eachroll 12 with a wrapper sheet 17, and this wrapper sheet 17 extends overthe opposite ends of the roll 12, as indicated at 18.

The wrapper 17 may also be coated or impregnated, as indicated at 19,with an anti-friction coating or impregnation so that the bottom end ofthe roll 12 will have a relatively slick or anti-friction surface forengagement with the surface 15, and the vertical sides of the rolls 12will also have a similar slick or anti-friction surface adapted toslidingly contact with the sheets on the sides and ends of the car 10.

In addition, the upstanding rolls 12 may also contact one with anotherand the slick or anti-friction surface of each wrapper will prevent anyscraping .action of one roll relative to the other as the rolls comeinto contact with each other.

The anti-friction coating 15 is herein disclosed as being formed on atleast one surface of the sheet 14, but it will be understood that thisanti-friction surface may in certa'in instances be formed directly onthe upper surface of the floor 11.

It will be understood that normally the floors of the freight cars arenormally relatively rough, but where these floors are relatively smooth,as where a new car is being used, or the floor has a metal surface, thecoating 15 may in such instances be applied directly to the lcar Hoor.

While l have shown the wrapper 17 as being coated or impregnated withthe anti-friction surface 19, it will be, of course, understood thatthis anti-friction surface 19 may, if desired, be applied only to one orboth ends of the rolls. In addition, in certain instances the ends orsides of the rolls may be uncoated and in other instances, the licorcovering may be omitted and the antifriction coating applied only to theends and/ or the sides of the rolls.

I do not mean to confine myself to the exact details ofconstruction-herein disclosed, but claim'all variations falling within the purviewof the 4appended claims.

2. In a method of loading newsprint rolls for Vshipment in a freight carthe steps which include covering the floor of a freight car with waxymaterial, and substantially filling the floor area of the freight carwith a plurality of newsprint rolls with their longitudinal axessubstantially, perpendicular to the lloor of the car for damage freerelative sliding movement thereon.

3.-In a method of loading newsprint rolls for shipment in a freight carthe steps which include coating the flat lower end of each of aplurality of newsprint rolls with an anti-friction material, andsubstantially filling the floor area of the freight car with the coatednewsprint rolls with their longitudinal axes substantiallyperpendicularto the floor of the car for damage free relative slidingmovement thereon.

4.

5. In a method of loading newsprint rolls for shipment in a'freight carthe steps which include covering the floor of a freight car with afibrous sheet having an anti-friction coated upper surface, covering theflat lower end of a plurality of newsprint rolls with an antifrictionmaterial, and substantially filling the floor area of the freight carwith a plurality of newsprint rolls with their longitudinal axessubstantially perpendicular to the licor of the car for damage freerela-tive sliding movement thereon.
